The invention discloses a hydraulic system, an energy recovery method and a construction machine. The hydraulic system includes: a front pump used for driving a first working device; a rear pump used for driving a second working device. The front pump and the rear pump are connected coaxially and are in transmission connection with an output end of a motor. The second working device includes a third direction valve, an inlet of the third direction valve is connected to an outlet of the rear pump, and a working port of the third direction valve is connected to a large chamber and a small chamber of a third oil cylinder. When the third oil cylinder retracts under the action of gravity, the rear pump is switched to a motor working condition, hydraulic oil from the large chamber of the third oil cylinder enters the rear pump in the motor working condition through the third direction valve, and the rear pump in the motor working condition is used for driving the front pump and/or the motor. The invention has the characteristics of a simple system structure, short energy recovery paths, a high energy recovery rate, good stability and the like.

This application discloses a safety-type controller applicable to engineering machinery, a control method, and an engineering machine in the engineering machinery field. The safety-type controller includes a multi-core processor including first, second and third processing cores. The first processing core is configured to run a BootLoader program. The second processing core is configured to run an application program to input or output a safety-related signal and read or write a safety-related or non-safety-related memory. The third processing core is configured to run an application program to input or output a non-safety-related signal, read or write a non-safety-related memory, and read a safety-related memory. The BootLoader program, the functional safety-related application program, and the non-functional-safety-related application program are run by separate cores in an isolated manner, thereby ensuring operating efficiency while improving safety.

For determining one or more material properties of an object (10), radiation of different wavelength ranges from at least one radiation source (2) is projected onto the object (10), in a temporal sequence, one wavelength at a time. The different wavelength ranges of radiation projected onto the object (10) and the temporal sequence are pre-set by an Artificial Intelligence (Al) model engine (8) provided by a data acquisition and evaluation system (7). Radiation reflected by the object (10) is captured by one or more multi-spectral image acquisition devices (12), and multiple images, and corresponding image data, are generated according to the reflected radiation of multiple wavelengths respectively. A set of raw data is formed to output to the data acquisition and evaluation system (7) for data analysis to determine one or more material properties of the object (10), wherein the set of raw data comprises the image data.

A thread-cutting mechanism of an embroidery machine, and a tube embroidery machine applying the same are provided. A movable knife frame provided at a periphery of a rotary shuttle can drive a movable knife to rotate around the rotary shuttle and coordinate with a stationary knife to cut a thread. The movable knife frame is rotatably provided at a periphery or one side of a driving shaft of the rotary shuttle. The movable knife frame is rotatably mounted on a needle plate seat, or on an embroidery machine body, at a corresponding location for cooperation with the rotary shuttle. The stationary knife is mounted on the needle plate seat, or on the embroidery machine body, at a corresponding location for cooperation with the rotary shuttle. This substantially reduces the space occupied by the movable knife. The thread-cutting mechanism is more compact, simple, compatible, and easy to use.
